Itunes starts as soon as I download a file; How do I turn this function off?

Tobimusic,

That is a function of your browser. Each browser has a way to tell it what to do with each kind of file. For example in Firefox it is found in Preferences > Applications, where you can set it for music files to "always ask" instead of "use iTunes." Other browsers have similar settings.

Hello Tobimusic,

Welcome to Apple Support Communities. It sounds like you're having trouble with iTunes beginning to play your music files when you download them. I'd be happy to share information that may help.

First, try these steps: 

• Restart you Mac: Log out, sleep, restart, or shut down your Mac.
• Start up in safe mode: Use safe mode to isolate issues with your Mac.
• Test this issue in another user account: How to test an issue in another user account on your Mac.

If the issue persists, please reply with the following details:

• Where are you downloading the files from?
• Are you attempting to import the files to iTunes or just download them to your Mac?

Take care.
